Metal Oxide 1W 4.7K Ohm Film Resistor

SMD Electrolytic Capacitors - 220uF/25V are surface-mountable capacitors used for energy storage in electrical circuits. They have a capacitance of 220uF, a voltage rating of 25V and a typical tolerance of ±20%. They are designed for use in a wide range of applications and are characterized by low leakage current and low equivalent series resistance (ESR). They have a compact SMD form factor and a typical operating temperature range of -40°C to +85°C, making them suitable for use in densely populated circuit board

The KY-008 Laser Transmitter Module is a compact laser diode module for DIY electronics projects. It has a 5mW, 650nm red laser diode that produces a highly visible red dot and can be powered by a 5V DC supply. The module includes a built-in current limiting resistor and has a standard 3-pin header for connecting to a control circuit. It is lightweight and easy to use, making it suitable for a variety of applications such as pointing, alignment, and experimentation. However, caution must be taken when using laser diodes as they can be harmful if not handled properly.
